MACHINE FOR COMPRESSING PLA STlC AND OTHER MATERIALS.

SPECIFICATION forming part of Letters Patent No. 279,384, dated June 1 2, 1883.

.Applieation filed "\pril 3,1883. (Nomodchi To all whom it may concern.-

Be it known that we, CHARLES HRMJE and THEODORE t. Bntzcnrr, citizens of the United States, residing at "ashington, in the District of'tolumbia, have invented certain new and useful Improvements in Machines for (Jonipressing'llastic and other Materials; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as. will enable others skilled in the art to which it appertains to make and use the same. Our invention relates to improvements in apparatus or machines for compressing plastic, pulverized, granulated, and other materials; and the object of our invention isto produce an apparatus or machine for forming cakes, cubes, cylinders, or other shaped articles from pure materials, so that they becomesolid and hard enough to be handled without breakin Our invention consists in apparatus or machines for compressing pulverized, granulated, or other materials, without the aid of any cement or binding materials, into molds of suitable size and shape, and applying to the compressed cubes or cakes, &c., a slight moisture, by means of a suitable spraying apparatus, so as to form a thin crust or film ot' the same material after the moisture has been evaporated; or the pulverized or granulated materials may besubjected to a slight moistening beforehand, either by pure water or water diluted with a little sugar, sirup, or other equivalent materials, and afterw ard compressed, which latter process will make the cakes or cubes solid and perfectly hard after the moisture has evaporated, all of which will be more full y described hereinafter, reference being had to the accompanying drawings, in which Figure Irepr'esehtsit side elevation ot' our niachine, partly in section. Fig. 2 is a vertical cross-section of the same on line :1 a. Fig. 3 is a horizontal section of the same. Figs. 4 and 5 In the drawings, A represents a suitable strong frame, on which a vertical flanged wheel, B, is secured to a horizontal shaft, 0, which revolves in bearings a or, attached to the frame A. The flange on said wheel B can either be made thick enough so as to form sutficientguidc for the plunger-s, or,as shownin the drawings,the're can be two flanges, b and c, of which the latter acts as a guide to the plungers D. Through these. flanges are bored or fitted the holes (I, in which the plnngeis travel, said holes being ar-. ranged radially. One or more rows of plungers may be em1.)loyedtwo rows being shown in the drawings-in which case the two abreastv or in line with each other are connected at their lower end by a shaft or axle, e which is pro- "ided with a whechf, on each end. A stat-ionllangcd plunger-wheel, fitted inside of the i latter and on the shaft (1, and by means of one or more strong angle-irons, g, is firmly secured to the frame.

On the upper side of the wheel B is fastened a short circular piece, F, the height of which '60 ary spider, E, of smaller diameter than theregulates the desired depth of the plunger: holes and the size of the product when the plungers are in place. Adjoining this circular piece 1: is an adjustable circular ,inclinc, G,-

-resting with its lower-end on the top of the frame A, and with its upper end extending un derthc end of the circular picec F, It is made adjustable by one or more set-screws, h, or their equivalents. On the outer side of the flange of the pl anger-wheel B, and opposite to the in clined plane G, is arranged the press-plate H,

held firmly against the face of the wheel B, at its -l owerefid', by one or more set-screws, i at or near its upper end are attached two braces, l', to the opposite ends of the frame, where they pass through lugs 7i! andarc adjusted by nuts I.

To the lowerside of the spider or inner wheel, E, is fastened a-circular inclined plane, 111, for the purpose of pushing out the cakes after they have been compressed. j I I ()n the opposite side from the press-plafieH is arranged a circular inclined plane, a, bolted or fastened firmly to the wheel E, and to the sides of said inclined plane n are fastened t-he retractors 0, which serve to pull the plungeis back' into position for filling theplungerholes ll.

On the top of the plunger-wheel B, and

is a suitable; feed box or hopper, L, arran ed either with revolving or perpendicularbr ies p to sweep the pulverized material into the plunger-holes. \Vithinthehopperisarranged ,and

a perforated pipe, 1*, through whichfinely-comminuted water is sprayed among the "material touching against the end of the press-plate H,

to slightly dampenit. The material may, however, be dampened before it is placed in the hopper, if desired. 7

A removable piece, 8, in the stationary wheel 5 E is provided for inserting the plungers into their respective holes.

Below the plunger-wheel is placed a1rendless belt or apron, K, revolving over suitable rollers or pulleys, and serv,es for the purpose of carrying off the cakes after they are discharged from the machine.

031C or more brushes, q, are arranged at a convenient place on the frame for the purpose of cleaning orbrushing off any small particles 1 adhering to the face of the wheelor to the ends oi the plungers.

The shaft 0 is provided with suitable pulleys or gearing to connect with the motive power and the endless belt.

2o The brushes p and q may be made adjustable to allow for wear, am.

.The operation is as'follows The material,

* either dry or moistened, is thrown into the hopper L, and as the plunger-wheel B revolves.

2 5 the material is swept into the plunger-holesd by means of thebrushes p." After the plungers D have passed the circular plate F they pass on to the inclined plane G, and as they travel up on it they compress the material against the d outer press-plate, H, until the lower end of said press-plate is passed, when the. compression ceases. The wheels ofthe plungers will then come. in contact with the inclined plane m,

vhich willforce them outward until theiroiit'er 5 endis flush-"with the outside or face of -the plunger-wheel B, and the compressed cake or block drops on the endlessbelt K and is carried I off, .The plnng'ers remain inthisposition until they have passed the brush q, which cleans the 0 face of the plunger-wheel as well asthe ends of the plungers, and when they come in line withthe lower end of the inclined plane-nthe extractors 0 will take holdon the upper side' I of the wheels f and gradually pull the plun-- gers back to their original position forfilling the plunger-holes (l with fresh material,

' This machine can also be employed for compressing such materials as sal-soda, 'alkalies, bicarbonate of soda,'&c.
